For the right use and safety of this product, please read through this manual prior to use.

Handling error may cause device trip, injury, or disaster.

1. Do not impose excessive pressure beyond the allowance.

2. Do not use corrosive measuring fluid.

This may cause pressure measuring element damage or rupture, resulting in measuring spill, 

 eventually human injury or surrounding destruction.

3. Avoid excessive load, vibration, or shock. The glass tube may be broken.

This may cause product damage or rupture to spill measuring fluid, resulting in human injury 

or surrounding destruction.

4. Keep the working temperature range.

In excess of the working temperature range, the measuring part may be damaged to destroy

the surroundings.

5. To detach the measuring instrument, be sure to close the valve to block the measuring fluid.

Measuring fluid spillage may destroy the surroundings.

6. When you are using oxygen for the measuring fluid, rely on the Use No Oil manometer.

Any oil reside in an ordinary product may react with oxygen, causing fire or explosion.

7. During site installation, be sure to follow this manual.

8. Do not modify the product by all means.

Be sure to consult with us prior to repair.

9. Be sure to close the valve and shut off the pressure before you open this product case.
